Chris Wilson Posted February 18, 2009 Share Posted February 18, 2009 Imagine 18,000 RPM and it becomes obvious what stresses are involved in a 4 stroke piston engine. Quote Link to comment Share on other sites More sharing options...

erol_h Posted February 18, 2009 Share Posted February 18, 2009 i wonder if you could see the pistons moving at 18,000rpm or would it be going soo fast it would seem like it wasnt moving. Quote Link to comment Share on other sites More sharing options...

bigbloodyturbo Posted February 19, 2009 Share Posted February 19, 2009 Bit OT here but would assembly lube be enough protection on all the bearings to mess about with it like that or do you think it was just a rejected block used for training purposes?

Chris Wilson Posted February 19, 2009 Author Share Posted February 19, 2009 Well oiled or greased bearings would be fine for a good few minutes as there's no loading on them, the pistons are just popping up and down creating no compression.

Swampy442 Posted February 19, 2009 Share Posted February 19, 2009 Theres a BIG valve head to go on that engine. Wonder what the piston speed is on an engine that size? Quote Link to comment Share on other sites More sharing options...

I see what you mean, look at the size of the valve relieves, they're huge! Its a wonder they dont go with 32valve heads. Quote Link to comment Share on other sites More sharing options...
